WATER COOLER.

Application filed` October, 31, 1925. v Serial No. 65,968;

My invention relates to improvements in water coolers, audit has particular relation to awater cooling'apparatus adapted for use in connection with drinking fountains and the like, where comparatively large quantities of cooled rwater are required to be delivered.

My present invention relates tothat type of water` cooler wherein there is provided a plurality of cooler units, connectedin series, through which units the drinking water is successively passed, said cooler units being disposed within, a tank, whereby the-ice or other refrigerant may be. superimposed thereon to effect the cooling of theA water passing through theunits.

More specifically considered', the present inventioncontemplates certain improvementsv upon the construction and arrangement of the cooler units shownin Letters Patent No. 1,493,016, dated May-6,1924, toy Harry K. Bush and Bertolet F. Frame.

The object, therefore,of my present invenT tion is to provide aniinproved formof cool- 4. ing unit adaptedto be arranged as aforesaid,

which will be Vmore simple and efficient than the cooler units of this typeheretofore pro vided, which may be inexpensively manufactured, and which may be readily assemf bled and dismantled as. desired, f

The nature and characteristic features of my invention will be more readily underf stood from the following description, `taken inconnection with the accompanying drawings forining part' hereof, in which:`

shown, 1Oisv a tank or cabinetI having mounted on the front thereof a drinking fountain 11 or delivery devic'erof any other preferred type.. lt should, ofcourse, be understood thatvthe, drinking fountainor other. deliver-y device, such as an Ordinar7 spigot, may be located elsewhererthan upon the front of the tank or cabinetl'Og-,if desired. A-pipe 12, extends from thefoungtaincor. other deliveryv device, said pipe 12 being arranged within the cabinet' and being connected to;A the cooler units which are lo,-

cated in the lowerv cabinet. 10. y A

The cooler units are preferably arranged in one or more rows,, and are-connected to each other in series by means of pipes 13, in a. manner which willy be hereinafter more fully set forth. Suitable piping 14: is proportion of thev tank or vided to connect the .ser-ies of units infone` row with the series in another rom said pipingincluding',l;in thearrangeinent thereof `the threaded portion 118, and av ,f gasket.A 2-1l is interposed between" the bottom of the cap member 19 and the upper surface cfr-the ledge 20, whereby, when saidv cap member is screwed tightly in; place, anl effective seal` at the top of the cooler unit is provided. i

rl`he cap member 19 isprovided with an upwardly extending portion 22, preferably polygonal in outline, having a central chambei' 28. A threaded opening 24 is-provided adjacent the chainber 23, forthe connection of the inlet pipe'thereto. There is also provided av threaded opening 25 in the bottom wall of the central chamber 23, Iwhereby a depending pipe 26 is mounted therein, -V

which pipe terminates adjacent the bottom of the body portion 17. The pipel is vopen at its Slower end. l

Arranged in' the leiter er smaller end of the body portion 17 of the cooler unit is an upward extension 27, having a plurality of curved vanes 28 associated therewith, so arranged that as the incoming water emerges from the end of the pipe 26, the same will be given a swirling motion against the sides of the body portion 17, thereby increasing the efficiency of the cooler unit and serving to thoroughly agitate and mix the water within the unit. Y

The cap-member 19 is also provided with a chamber 29, in direct communication with the interior of the body portions of the unit and having a threaded outlet opening '30,

ywhereby the outlet pipe may be connected therewith so as to permit the water to pass from the cooler unit.

It will, of course,be understood that the ice, which is preferably in block form, rests on the tops of the several unitswliich are arranged in the bottom of the tank or cabinet, and the bodies of the units are submerged inthe water which results from the melting of the ice, which may be drawn off by an overflow (not shown) at the desired height. In this manner, the cooling effect of the ice is applied to the exterior surfaces of the cooler units, thereby effecting the cooling action in an efficient manner without contamination from impurities contained in the ice.

The body portionf17 of the cooler unit is preferably made of cast iron or the like,y

and enameled on its inner and outer surfacesIto prevent corrosion, theshape being such that said inner and outer surfaces may be properly coated with porcelain or burnton enamel of a lasting character. The cap member 19 is preferably made of a nonlcorrosive material such as brass, although, if desired, the same may be made of enameled Cast iron in a manner similar to ther body portion of the unit.

For the purpose of facilitating the insertion and removal of the cap member 19 with respect to the body portion 17, the body por.- tion is provided with a plurality of lugs or projections 31 having vertical faces, whereby the body portion of the unit may be firmly gripped by a suitable tool while threading the cap member in or out of the body portion.

It will be noted that, by the foregoing arrangement, there is provided a sanitary cooling apparatus which may be readily assembled and easily dismantled for therpurpose of thoroughly cleansing the interior surfaces thereof, and in which, when in operation, the cooling action will be efficiently carried out by reason of the peculiar arrangement and conformation of the various parts.

Having thus described the nature and characteristic features of my invention, what I claim as new and desire toj secure Vby Letters Patent, is:

1. Ina water cooler, a unit comprising a hollow frusto-conical casing integrally closed at its smaller end, said smaller end of thev casing having internally arranged Acurved vanes adapted to impart a swirling motion to water passing Vthrough the unit, a removable cap member secured in the Alarger end of said casing, said Cap member having two chambers, an inlet pipe Connected to the cap member and in communication with one of said chambers, a pipe mounted in said cap member in communication with said chamber and extending within the casing and terminating adjacent the smaller end thereof, and an outlet pipe connected to thev cap member and communicating with the other chamber thereof.

2. In a water cooler, a unit comprising a hollow frusto-conical casing integrally closed at its smaller end, said smaller end of the casing having an internal extension and curved vanes associated therewith adapted to impart a swirling motion to water passing through the unit, a removable cap member secured in the larger end of said casing, said cap member having two chambers, an inlet pipe connectedv to the cap member and in communication with one of saidv chambers, a pipe mounted inl said cap member in communication with said chamber and extending within the ycasingl and terminating adjacent the smaller end thereof, and an outlet pipe connected to the cap member and communicating with the other chamber thereof.

In 'testimony whereof, I have hereunto signed my name.
